Not sure!!

Dawn • Hello, I`m 34 years old my wonderful husband is 34. We are new at this but TTC. I have a kid, trying 4-1 with him.
My family and I rescued a cat that was abused.  She has no name yet but I got her from the animal shelter so she is spayed, up to date on shots, and flea dipped and dewormed.  Anyway I just had an allergy test done last week and my test being allergic to cats came back negative.  I am actually allergic to dogs!! Lol  anyway we got the cat and I am starting to feel like I'm allergic to her.  I itch and have a stuffy nose.  I'm not sure if it's in my head or if it's because of the cat. Now I haven't sneezed or had watery eyes so I'm confused.  I guess my question is could my test have been wrong?  It was a skin and blood test that came back negative!! 😒
